Product Description
The main uses of phenolphthalein are: 1, pharmaceutical industry pharmaceutical raw materials: pharmaceutical laxative, can stimulate the intestinal wall, cause intestinal peristalsis to promote defecation. 2, for organic synthesis: mainly used for synthetic plastics, 3, for alkali indicator, non-aqueous titration indicator, chromatography reagent.
Phenolphthalein appears as white or yellowish-white to pale orange fine crystalline powder. Odorless. Aqueous solution is acidic. Colorless to pH 8.5; pink to deep-red above pH 9. Colorless in presence of large amounts of alkali. Tasteless.Phenolphthalein is an organic compound used as a laboratory reagent and pH indicator. Phenolphthalein exerts laxative effects by stimulating the intestinal mucosa and constricting smooth muscles. However, phenolphthalein is no longer used as a laxative due to the suspected carcinogenicity of this compound.
Application and Function
1, the pharmaceutical raw materials in pharmaceutical industry: it is suitable for habitual stubborn constipation, including tablets, suppositories and other formulations.
2, it can be used for organic synthesis: mainly used in synthesizing plastics, especially in synthesizing the phthalazinone poly aryl ether ketone poly aryl ether ketone polymers. This kind of polymers, because of its excellent heat resistance, water resistance, corrosion resistance, heat aging resistance and good processability, fibers, coatings and composites made of it are widely used in the fields of electrical and electronic equipment, transportation and aerospace, atomic energy engineering .
3, used as acid and alkali indicator, non-aqueous solution titration indicator and chromatography analysis reagents.
